SHAFT-HANGER.

SPECIFICATION forming part of Letters Patent No. 416,197, dated December 3, 18891.

Application filed December 6, 1888. Serial No. 292,943- (No model.)

To all whom t may concern.-

Be it known that I, FREDEEICH W. ULRICH, a citizen of the United States, residing at Rock Falls, in the county of IVhiteside and State of Illinois, have invented certain new and useful Improvements in Shaft-Hangers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had' to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention has reference to improvements in shaft-hangers; and it consists, more essentially, in a provision for forming the bracket or upper portion of the hanger in two parts for ease and convenience in placing; second, in removably seatin g the pendent tube in said upper portion, and, thirdfin means for seating removably and adjusting vertically the yoke which supports the shafting.

In the drawings, Figure 1 is a perspective of a hanger embodying my invention, viewed in the line of the shafting. Fig. 2 is a detail of the upper portion thereof, showing the parts separated.

A is a bracket, formed in t-wo parts B by dividing vertically in the line of the axis of the depending central sleeve O in said bracket. The bracketA is formed of the usual horizontal portions D D, adapted to be fastened to the usual shaftstrin gers attached to the ceiling or joist, and provided with the usual slotted bolt-seats (not shown) for the lateral adjustment of said hanger. Said bracket is also provided with the downwardly-extending sleeve C, adapted to receive the vertical pipe or stem E. Bolt-holes F are formed transversely in the sleeve C, centrally through each half thereof. The pipe E is an ordinary gastube, and is adapted to be inserted within the sleeve C, and is provided with a series of bolt holes G, and when the holes G are placed so as to communicate with the holes F in the sleeve C a transverse bolt His passed through the two halves of the sleeve C and through the pipe E, and performs the double function of clamping the parts B B of therbracket A together and upon the pipe E, and also of supporting the latter.

The advantage of forming the bracket Ain two parts arises from the fact that these hangers are sometimes necessarily of great weight, and therefore the holding of them in place while being fastened to the stringers is very inconvenient and laborious, while by forming said bracket in the two parts shown the amount of weight to be sustained during the process of fastening is reduced just one-half; also, the goods can be shipped in a knockdown condition. It will be noticed that the contiguous inner faces of the parts IB B of bracket A have centrally formed therein, respectively, ooncavities J, so that when said faces are brought nearly into contact the two concavities furnish a circular seat for the upper end of the pipe E. The concavities J are in the aggregate somewhat less than the circumference of the pipe E,` so as to permit the bolt H to have a clamping effect upon the pipe E before the adjacent faces of the sleeve 'C shall come into mutual contact.

IIeretofore the bracket portion of said hanger and the dependent stem E have been formed integral, which largely increased the trouble and expense of making the saine, and also rendered the same heavier and more inconvenient to ship and handle after it Was made. -In my invention, by forming the said parts separately, I am enabled to use gas-pipe for the pipe E, which renders the construction of said parts not only more simple, but less expensive, and, further, by the provision of the series of holes G in said pipe E, I am enabled to vertically adj ust said pipe, as occasion may require, by the insertion of the bolt II through the different holes G.

K is a shaft-yoke provided at its outer end with the usual lateral arm R, to support the usual shaft-box L, and at its inner end with the sleeve M, adapted to be passed over and to be vertically adjusted upon the lower end of the pipe E. The vertical adjustments of the sleeve M are accomplished by the lower nut N, provided with interior threads adapted to be screwed upon conforming threads formed on the exterior of the pipe E at the lower end thereof, which nut N forms the bottom support to the sleeve M. The sleeve IWI can also be rotated axially upon the pipe E for adj ustment in the horizontal plane of the shaft-box L, and is held in place by the set-screw O, seated in the sleeve M, and adapted-to have IOO its inner end forced against the exterior of the pipe E within the,sleeve M. The nut N is provided with radial slots P, for the insertion of a bar or rod as a means of turning said nut, or such nut may be of the usual rectangular formation.

The removability of the sleeve M is an advantage in shipping and also in placing the hangers, as the bracket A and pipe E can be first attached to the buildingand the sleeve M subsequently put in place.

What I claim as my invention, and desire to Secure by Letters Patent of the United States, is

1. In a shaft-hanger, the combination of the bracket A, formed of the parts B B, provided with concavities J and bolt-hole F, the pipe E, provided with one or more bolt-holes G,

and the bolt H, substantially as shown, and for the purpose described.

2. In a shaft-hanger, the combination of the bracket A, provided with the sleeve C, and transverse bolt-holes F therein, the pipe E, provided with the transverse bolt-holes G in its upper portion and the peripheral threads on its lower end, the bolt H, the yoke K, provided With the sleeve M, vertically and horizontally adjustable on said pipe, the shaftbox L, and the supporting-nut N, substantially as shown, and for the purpose described.

In testimonyfwhereof I affix my sign ature in presence of two Witnesses.
